铅锌尾矿生态修复技术研究进展

Research Progress in Lead-zinc Tailings Ecological Restoration Technology

铅锌尾矿养分含量低下、物理结构差、重金属含量高以及重金属复合污染等因素已构成金属矿区生态修复的重要难题。针对铅锌尾矿污染的特点,介绍了几种主要的铅锌尾矿修复技术:基质改良技术、植物修复技术和植物-微生物联合修复技术,分析了不同修复技术的特点及其存在的问题,在此基础上,对铅锌尾矿库修复技术的未来发展进行了展望,旨在为铅锌尾矿库生态修复工程提供理论依据和技术支撑。

Lead-zinc tailings nutrient content is low, poor physical structure, a high content of heavy metals and heavy metals compound pollution factors constitute important problems of ecological restoration in metallic ore districts. According to the characteristics of the pollution of lead and zinc tailings, the paper introduces several main lead-zinc tailings remediation technologies： substrate amendment technology, phytoremediation technology and joint restoration technology, the paper analyzed the characteristics of different repair technology and its existing problems, and on this basis, the future development of lead-zinc tailings restoration technology is prospected, provide the oretical basis for lead-zinc tailings restoration technology and technical support.
